Since early September, Dunn, at KBIA, and Spencer, at KOPN, have been sniping at each other through the press, arguing about who had what programming first as they battle for listeners.
With a $1.3 million budget and 4,500 subscribers, the University of Missouri-owned KBIA, 91.3 FM, is the giant public station in this college town.
The show came with no pre-promotion, a decision Spencer says was based on fear that KBIA would mirror his programming.
So did KBIA. By Monday morning, KBIA had pulled its 9 o'clock hour of classical music and added the Diane Rehm show.
Why doesn't KBIA pick others of the hundreds of shows available to public radio if it wants to increase its new-stalk content?
KBIA has made overtures to buy the license of KCOU, a small station run by university students.
But in the next breath he says his station has been "bloodied" by KBIA "thugs."
"It just left a really bad taste in my mouth," King says, adding he was particularly upset with KBIA's "hostile" reaction.
Local newspaper accounts have painted KBIA as a bully, mirroring KOPN's programs to shut the little guy down, a portrait Dunn says is distorted.
